sPncInIcATIoN forming part of Letters Patent No. 643,382, dated February 13, 1900;. Application filed December 3 l, 1898. Serial No- 700,792. (No model.)

To all whom it may concern.-

Be it known that I, J AMES H. KLIPSTEIN, a citizen of the United States, residing at Marshall, in the county of Fauquier and State of Virginia, have invented a new and useful Stove, of which the following is a specification.

The purpose of the present invention is to secure economy in the consumption of fuel and make available a maximum amount of the heat, which is generally lost by the same passing off with the products of combustion through the smoke-pipe.

The subject-matter of the invention is a stove of the wood-burning variety and constructed chiefly of sheet metal, and in its organization the stove comprises a hot-air drum or space between the fire-box or combustionchamber and the outer shell or body of the stove, said drum or hot-air space being surroundedby a space through which the smoke and products of combustion pass on their way to the smoke-pipe, thereby separating the greater part of the heat from the gases by radiation and convection prior to the escape of said gases into the atmosphere by way of the smoke-pipe.

For a full understanding of the merits and advantages of the invention reference is to be had to the accompanying drawings and the following description.

The improvement is susceptible of various changes in the form, proportion, and the minor details of construction without departing from the principle or sacrificing any of the advantages thereof, and to a full disclosure of the invention an adaptation thereof is shown in the accompanying drawings, in which- Figure 1 is a perspective view of a stove for attaining the objects of this invention. Fig. 2 is a vertical central longitudinal section thereof. Fig. 3 is a plan section of the complete stove about on the line X X of Fig. 2. Fig. 4 is a perspective View having the outer shell and the top removed. Fig. 5 is a side elevation of a modification, parts being broken away. Fig. 6 is a transverse section of the construction shown in Fig. 5. Fig. 7 is a detail View of the lower end of the vent-pipe, the full lines showing the parallel slits and the dotted lines showing the portions separated by the slits bent upwardly, forming the guards. Figs. 8, 9, and 10 show different arrangements of the flanges for securing a circulation of the products of combustion. Fig. llis a detail View showing an air-tube extending across the smoke-space for supplying air to the air-space.

Corresponding and like parts are referred to in the following description and indicated in the drawings by the same reference characters.

The stove in its general appearance may have any desired outline, and, as shown, is of oblong form, being oval or elliptical in plan View, which is the shape found most desirable in heaters of this type.

The stove is mounted upon legs 1 in order to support it a distance from the floor or other surface, so that air may circulate beneath the bottom and pass upwardly through openings in said bottom into and through the air space or drum. The body or outer shell 2 is mounted upon the bottom 3 and is secured thereto in any of the usual ways and is closed at its upper end by a top 4, which is supplied at one end with a collar 5, to which is fitted a smoke-pipe (not shown) in the ordinary way. An opening is had in the top 4 and is closed by a cover 6, and admits of fuel being placed into the fire-box or combustion-chamber 7.

The hot-air space or drum is formed by inner and outer shells 8 and 9, disposed so as to inclose a space between them, said drum being of a shape corresponding to the outline,

of the stove and having the shells joined at their ends arid separated, as shown at 10. The shells 8 and 9 are concentric and the space formed between them is of uniform width throughout its length. A plate ll extends across the space 10 and is joined to the end portions of the outer shell 9 and is provided at its lower end with an opening 12 and at its upper end with a corresponding opening controlled by means of a damper 13. The damper 13 is vertically disposed, and its stem 14 passes .through an opening in the top 4:, thereby admitting of the damper being operated from a point without the stove. The space inclosed by the hot-air drum or by the inner shell 8 thereof constitutes the fire-box or combustion-chamber 7, and air is supplied to the lower end of this space by means of a 2 v ceases cut-away side ofthe vent-pipe, so as to admit tion.

air into the fire-box for supporting combusof the'vent-pipe and can be turned so as to close the vent-pipe or regulate the draft to The lower end of the vent-pipe is the portions formed between the slits are bent about at right angles to the length of the pipe and project into the fire-box, forminga series of guards 18, which prevent the fuel from crowding into the opening and shutting off the draft. These guards 18 are radially disposed and are spaced apart at their outer ends and insure the air being properly admitted into the'fire. These guards 18 may of course be made of cast-iron.

A space 19 is formed between the hot-air drum and the body or outer shell 2'andis in communication with the smoke pipe (not, shown) by means of thecollar 5 and with-the fire-box through the opening 12 and the opening controlled bythe damper 13. By having the smoke-pipe located at the end remote from the opening 12 the heat and products of combustion are compelled to pass through the smoke-space 19 before they can escape, and the smoke and gases in their travel through this space heat the body 2 and the outer wall or shell 9 of the hot-air drum, whereby the air in contact with said shells is heated by. ra diation and convection. In order to retard the passage of the hot air andgases through thespace 19, plates, flanges,or strips 20 are provided and extend across the space 19 formed between the shells 2 and 9. The lower plate or flange is interrupted at the rearend of the stove, as indicated at 21, and. the upper plate or flange is interrupted at the front end of the stove and at a point diametrically opposite the space 2l.formed between the intercepted ends of the lower flange. W'hen the fire is burning. briskly or is well started and it is required to utilize the heat to the best possible advantage, the damper 13 is closed, thereby compelling the hot air and products .of -combustion to pass from the fire-box out through the opening 12 andinto the space below the lower flange or plate20 to the rear of the stove, and thence into the space formed between the two flanges or plates toward the front of the stove and into the space formed above the upper flange or plate and again rearward and out through the collar 5 and the smoke-pipe The products of coinbustioni and hot air in making this tortuous path have 'ister with the hot-air space.

The cap 16 is provided with a'handleand is rotatably mounted upon the upper end the greater part of the heat eliminated therefrom by radiation, so, that but very little heat is'lost, the greater part being made available for heatingpurposes.

The cold air enters thelower end of the space formed between the shells comprising the hotair drum through. openings 22 formed in the bottom 3 and, passing through said space, is heated and escapes through corresponding openings 23 inthe top 4, opposite and in regof the invention cold air will be supplied to the hot-air drumthrough lateral openings or passages 24 extending through the shells 2 and 9. In this construction the plates flanges, or parts 20 will be duplicated and the com panion strips or plates arranged inv close relation, so as to formbetween them the pas- In some forms sages 24, which openinto the air-space of the drum andout through the body or shell 2. The-flanges, plates, or-strips20 maybe-horizontal or slightly inclined, as desired, and theirnumber may be variedaccording to the size and arrangement of the stove.

Fig. 10 shows the flanges running spirally aroundthe drum. The smoke-pipe may communicate with the top, front, orback of the stove-bod y, according to the style of the stove. Air may be supplied to the air-space 22 by lateral tubes'22, as indicated in Fig. 11. A partition 25 subdivides the air-space 22 and is formed of iron and acts to-absorb. heat and tojgive it out, gradually, and thus maintain a more or less constant temperature under flue tuations i-n'temperatureof the stove proper.
